Inductors are electronic components that store energy in a magnetic field when an electric current flows through them. They are constructed with a wire wrapped around a core of ferromagnetic material such as iron or ferrite.

The unit of measurement for inductance is the Henry (H), named after the American physicist Joseph Henry. A 1 Henry inductor stores 1 joule of energy when a current of 1 ampere flows through it.

Inductors are used in electronic circuits to filter signals, store energy, create magnetic fields, and many other applications. They are commonly used in power supplies, audio filters, oscillators, amplifiers and many other circuits.

When an electric current flows through an inductor, a magnetic field is created around the coiled wire. This magnetic field stores energy and opposes any change in electrical current. This means that when the current is turned off, the magnetic field starts to dissipate and the stored energy is released back into the circuit.

Inductors can also be used in conjunction with capacitors to create resonant circuits, which can be used in oscillators and frequency filters. Resonance occurs when the frequency of the electrical signal is equal to the natural frequency of the resonant circuit.

Inductors have some limitations, such as their electrical resistance, which can dissipate energy in the form of heat. They can also generate electromagnetic interference in other nearby components. Therefore, it is important to choose the right inductor for the desired application and position it correctly in the circuit.
